In the name of Allah, Most Gracious, Most Merciful.
Narrated Abu-Huraira (may Allah be pleased with him): ‘Allah’s Messenger (May Allah exalt his mention and protect him from imperfection) said: “If the people knew (the reward for) pronouncing azan and for standing in the first row (in congregational prayers) and they found no other way to get there except by drawing lots, they would draw lots, and if they knew (the reward of) Zohr Prayer (in the early moments of its stated time) they would race to it (go early), and if they knew the reward of Isha and Fajr Prayers in congregation, they would come to offer them even if they had to crawl.'” (Bukhari)
